You remember when your first child was around 2 and you realized they had run away from you in the middle of Target, and you spent the most terrifying 30 seconds to five minutes of your life searching for them before you found them hiding in the middle of a rack of graphic tees? Expect to feel that way the entire time you're chaperoning, only the prospect of losing someone else's kid might be even worse than misplacing your own (you're pretty sure that one will come back).
